Specification of Letters Patent.

Patented May 2, 1922.

Application filed June 16, 1920. Serial No. 389,362.

To all whom it may concern:

Be it known that I, Gnoncn GUARD, a citizen of the United States of America, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have 111- vented. certain new and useful Improvements in lVindows, of which the following is a specification.

My present invention relates'generally to windows and more particularly to a construction and arrangement providing for ready ventilation as well as for convenient cleaning of the sash glasses, my primary object being the provision of a conventional double sash structure in which each sash may in turn be reversed for cleaning its outside surface, with the entire window opening closed during each cleaning operation.

The foregoing and certain other objects, together with the resulting advantages of my invention will more clearly appear in the course of the following description wherein reference is made to the accompanying drawings forming a part of this specification. In these drawings,

Figure 1 is an elevation looking at the inner side of the window,

Figure 2 is a vertical transverse section taken substantially on line 2-2 of Figure 1,

Figure 3'is a similar view with the slide frame of the lower sash raised and the sash turned down,

Figure 4 is a horizontal section on line lt of Figure 2,

Figure 5 isa vertical section through the lower sash and its slide frame looking in the opposite direction with respect to Figure 2, and with the sash tilted for ventilation,

Figure 6 is a sectional plan view of the upper sash with its top strip removed,

Figure 7 is an enlarged horizontal section on line 77 of Figure 5.

Figure 8 is a vertical section on line 88 of Figure 7 Figure 9 is a side view partly broken away and in section of the lower slide frame,

Figure 10 is a similar View of the lower sash,

Figure 11 is a detail perspective view of one of the locking rods.

Referring now to these figures, my invention proposes the use of upper and lower sashes of similar size and form, these sashes being indicated at 15 and 16 and each being cut away at its lower corners to form rccesses 17 having plates 18 secured therein as bymeans of screws 19, these plates having plvot pins 20 projecting laterally beyond the sash sides as best seen in Figure 10.

Each sash also has a groove 21 in its upper edge extending for its fullwidth as plainly seen in Figure 5 and is provided with a recess 22 centrally between its sideedges communicating with the central portion of the groove. This groove receives a pair of out- 7 wardly and oppositely projecting locking bars 23, having inner laterally projecting finger pieces 2% which project through the apertures of a plate 25 covering the recess 22. A spring 26 is disposed within the recess 22 and is compressed between the two finger pieces 24 to normally hold the rods 23 in outer operative positions with their outer ends projecting slightly beyond the sash sides. The outer portions of the rods 23 pass between vertical guide pins 27 and the rods are each confined within their groove 21 by a cover strip 21 which extends along the upper edge of the sash and is suitably secured thereto. 7

The sashes 16-and 15 are mounted respectively within slide frames 28 and 29, and each of these slide frames is of inverted U- shape, the two frames being of identical structure except as to the thickness of their upper cross bars, the upper cross bar of the outer slide frame 29 being somewhat thicker than that of the inner slide frame in order that when the inner sash and its frame, the normal closed position of which is seen in Figure 2, are shifted upwardly, the outer sash can be lowered from its normal position to such a point that the upper edge of the outer sash 15 will be slightly below the plane of the lower edge of the inner sash.

Each of the slide frames has two side portions 30 and an upper cross bar 31, the side portions being provided with openings 32 and 33 respectively adjacent to the upper and lower ends thereof and in opposed pairs for the reception ofthe projecting ends of the locking rods 23 and the pivot pins 20 of the sashes.

Eachslide frame is preferably constructed of sheet'metal bent to form inner and outer walls 34 and35 along both its side and top portions, one terminal edge of the sheet metal being extended along the outer face of the frame to form a sash limiting flange '36 extending along its cross bar 31 and along the major portions of its sides 30, being cut away however adjacent to the lower ends of the sides as clearly seen in Figures 5 and 9 in order that both sashes may be free to swing inwardly and downwardly upon release of the locking rods, upon the pivot pins 20.

The inner sash 16 is moreover cut away at one side to receive one pivoted end of an adjustable supporting arm 37, whose opposite end has an angular headed pin 38 extending through a vertical slot 39 in the corresponding inner side wall of its slide frame 29, which is provided with notches 40 at spaced points along one side of the slot 39 arranged to be engaged by a knife edge of the pin 38. The slot 39 communicates at its lower end. with an enlarged opening 41 through which the head of the pin 38 may be inserted or withdrawn, so that while the arm 37 is thus adapted to support the inner sash 16 at various angular positions one of which is seen in Figure 5, it is also adapted to be entirely withdrawn from the slide frame 29 to permit the inner sash to be swung inwardly and downwardly to the position shown in Figure 3.

Thus with the sashes in their normal positions of Figure 2 and with the grooves 42 engaging guide strips of the sides ll of the window casing it is obvious the slide frames, with their flanges 36, effectively prevent the entrance of weather around the tops and sides of the sashes and it is thus evident that the window opening will be effectively closed and sealed. If ventilation is desired the finger pieces 24: of the locking rods 23 of the inner sash are pressed toward one another against the tension of spring 26 and the sash thus released for more or less tilted position with respect to its slide frame 29 under control of the adjusting holding arm 87.

When the windows are to be cleaned, and after the inner surfaces of the sash glasses have been cleaned for instance the inner sash and its slide frame are shifted vertically to the top of the window frame and the inner sash. released and swung downwardly to the position of Figure 3 so that by then pressing its lower edge downwardly against the sill a5, the outer'face of the sash glass is exposed to the room for convenient cleaning with the window opening completely closed. Similarly when the inn ner sash has been thus entirely cleaned itis lowered slightly and the inner sash again swung upwardly and locked in normal position, after which the outer sash is lowered until its upper edge is below the lower edge of the inner sash in the upper position of the latter. The outer sash is then released and swung inwardly and at the same time pressed upwardly with its slide frame until it is straightened in a vertical position and can be lowered until its lower edge enarsen? gages the sill it, thus reversing the sash so that the normal outer face of its glass is exposed to the inside of the room for convenient cleaning. It will be noted that during this operation as in the case of: the inner sash the window opening will be entirely closed during the cleaning operation on account of the fact that the sides of the reversed sashes coast with the inner and outer stops of the window casing. Thus this cleaning operation may be effectively carried out in its entirety without admitting air from the outside except during the mere adjustment or movement of the sashes to and from the positions described, and to this extent as well as the fact that both the sashes and the slide frames thereof are of so nearly identical formation as to permit of more ready manufacture and assemblage, my invention is an improvement over existing devices of this nature and will be generally more effective and efficient in use for the purposes stated.

I claim:

1. The combination with a window casing having guides, of a pair of inner and outer slide frames engaging said guides and each formed of inverted U-shape including side portions and an upper cross bar of hollow form and having flanges along the cross bar and the major portions of the sides, said slide frames having their inner walls provided with ooenings adjacent to the upper and lower on s of their side portions, and inner and outer sashes within the slide frames, each sash having lower laterally projecting pivot pins entering the lower apertures of its slide frame and upper spring controlled and manually releasable lockingrods the outer ends of which are engageable in the upper apertures of its slide frame, the outer sash being movable downwardly to a position wherein its upper edge is below the lower edge of the inner sash when the latter isshifted to the top of the casing.

2. window sash having laterally projecting pivot pins at the lower ends of its sides and having spring controlled manually shiftable locking rods along top whose outer ends normally project beyond the upper ends of the sash sides, and a slide frame of inverted ll-shape formed of bent sheet metal having terminal edges forming inwardly projecting flanges along the top and the major portions of the sides th .reof, the outer walls of the sides of the slide frame having guide means and the inner walls thereof having openingsadjacent to their upper and lower ends for respectively receiving the locking rods and the pivot pins of the sash, as described.

In testimony whereof I have atlixed my signature.

GEORGE GUARD.
